A method of making a multi-layer circuit board that has a first film and at least two more films, second and third films, each being made of a thermoplastic polymer capable of forming an optically anisotropic melt phase, the first film having a low melting point, the second and third films having respective melting points higher than the melting point of the first film and at least one of the second and the third films having a circuit pattern thereon, and the first to third films are thermo compressed together with the first film interposed between the second and third films. This method entails causing at least one of the circuit patterns on one of the second and third films to contact an opposing surface of the other of the second and third films through the first film during the thermo compression bonding of the first to third films.

A process for producing vinyl acetate polymers comprises, after polymerization of at least one monomer comprising vinyl acetate, adding a conjugated polyene having a boiling point of at least 20&deg; C. Saponified products of the vinyl acetate polymers obtained by this process can give molded articles causing little coloring and generation of gel-like agglomerates.
